Paper Mache Replica Blocks

The idea is to allow players to build with otherwise inaccessible blocks (such as bedrock, budding amethyst, end portal frames, etc) by making replicas of them. These replicas are purely decorative and lack the functionality of their real counterparts. This could also apply to rare and/or finite blocks such as ores and ancient debris. Paper mache can be crafted with 8 paper and 1 slime ball. Using paper mache on a valid block will turn it into a replica, which can then be placed. These replica blocks can be turned back into paper mache using the crafting grid.
